Definitions

  • wireless networks such as but not limited to, wireless networks operating according to an Institute for Electronic and Electrical Engineers IEEE) 802.16 standard
  • a connection is shared between all packets that carry the same protocol and have the same quality of service (QoS) requirements (and should use the same QoS parameters). That is, if a MS has to support QoS (QoS) requirements (and should use the same QoS parameters). That is, if a MS has to support QoS (QoS) requirements (and should use the same QoS parameters). That is, if a MS has to support QoS (QoS) requirements (and should use the same QoS parameters). That is, if a MS has to support

  • FIG. 1 is an illustration of a MAC SDU according to an embodiment of the present invention.
  • FIG. 2 provides a system according to embodiments of the present invention.
  • plural and “a plurality” as used herein may include, for example, “multiple” or “two or more”.
  • the terms “plurality” or “a plurality” may be used throughout the specification to describe two or more components, devices, elements, units, parameters, or the like.
  • a plurality of stations may include two or more stations.
  • Embodiments of the present invention provide adding a protocol type field to the wireless network (such as WiMAX) packet (for a new type of convergence sublayer [CS]), to enable sending several different protocols over the same flow.
  • WiMAX wireless network
  • CS convergence sublayer
  • Embodiments of the present invention provide adding a new CS type in which an extra field is added to the WiMAX (it is understood that the present invention is not limited in this respect) SDU (much like the PHSI field is added to WiMAX SDUs on flows where PHS is enabled) to indicate which higher layer protocol is carried in the WiMAX SDU payload.
  • Embodiments of the present invention may provide a CS specification parameter specifying the CS that the connection being set up shall use the following.
  • Embodiments of the present invention provide a MAC SDU format as shown in FIG. 1 generally as 100. Once classified and associated with a specific MAC connection, higher layer PDUs 140 shall be encapsulated in the MAC SDU 1 10 format.
  • the 8-bit PHSI (payload header suppression index) field 130 shall be present when a PHS rule has been defined for the associated connection.
  • Embodiments of the present invention may provide an 8-bit Protocol ID field shall be present when a multiprotocol flow is defined for the associated connection. Support for multiple protocols on the same flow are set forth according to embodiments of the present invention. In order to transport several types of protocols, over the same MAC connection the multiprotocol flow can be used.
  • the receiver must identify the protocol to correctly forward the service data unit (SDU). For instance, but not by way of limitation, if the information carried by the SDU is a RoHC packet, it should be forwarded to the RoHC decompressor. The receiver does this according to the Protocol ID field which is the first byte of a Multiprotocol flow connection as depicted in FIG. 1. Once the protocol type of an incoming packet is determined, the appropriate classification rules are applied to the packet and the correct service flow is identified. It is then optionally forwarded to the header suppression mechanism (PHS or RoHC) and then mapped to the MAC SAP using the format described herein. The protocol ID content is set by the transmitter by the protocol identified before the classification rules were applied and according to the Table below.
  • SDU service data unit
  • FIG. 2 a system diagram according to embodiments of the present invention, in which a mobile station (MS) 220 and applications 230 are collocated in a mobile user terminal 210, such as, but not limited to mobile phone, laptop, PDA etc.
  • MS and a base station (BS - also referred to herein as an access point (AP)) 240 may communicate wirelessly.
  • Both MS and BS may utilize transceivers that operate according to the embodiments set forth herein.
  • a further embodiment of the present invention provides a computer readable medium encoded with computer executable instructions, which when accessed, cause a machine to perform operations comprising supporting multiple protocols in a wireless network, such as, but not limited to, a network operating according to an Institute for Electronic and Electrical Engineers IEEE) 802.16 standard by adding a new convergence sub layer (CS) type in which an extra field is added to an 802.16 service data unit (SDU) to indicate which higher layer protocol is carried in a 802.16 SDU payload.

Abstract

Un mode de réalisation de la présente invention porte sur un procédé d'assistance à des protocoles multiples dans un réseau sans fil fonctionnant selon une norme de l'Institut des Ingénieurs Électroniciens et Électriciens (IEE)E 802.16, comprenant l'addition d'un nouveau type de sous-couche de convergence (CS) dans lequel on ajoute un champ supplémentaire à une unité de données de service (SDU) 802.16 pour indiquer quel protocole de couche supérieure on exécute dans une charge utile SDU 802.16.
